Week 1 against the Pittsburgh Steelers proved why Haloti Ngata is the most valuable defender on the Balitmore Ravens.

Ngata clogged up the Pittsburgh running lanes which allowed Ray Lewis and Terrell Suggs to make some key plays, and he forced an enormous fumble by running back Rashard Mendenhall after delivering a punishing blow.

Ngata also put some pressure on Big Ben, which forced some key interceptions by the Ravens secondary.

Since being drafted in 2006, Ngata has been considered one of the best defensive lineman in the game.
